查询词典 optical

We made an experimentally and theoretically research on SRS at low temperature (about 80K-190K) in highly single mode circular optical fiber. The experimental apparatus is designed and the principle of experiment is given. The SRS in highly single mode circular optical fiber is measured at different temperature. A series of SRS spectra is get in low temperature. On base of the spectra, we get a curve of the frequency shift and the half breadth with the temperature fluctuation.
